    keyword=HAND (e,e'pn) BG for 750MeV/c and 625MeV/c kinematics

    Below is the HAND TOF spectra for the curent and old kinematics. We can't see peaks yet but it can help understand the BG.

    The cuts upplied here are the same as in the BB analysis.

    If I "free" the target cuts and incluse the walls I do see a small peak. I prefere keeping the "harder" cuts and wating for tomorrow to see a peak from the 4He itself.
